Solvion

This medication is a combination of three drugs: Ambroxol (mucolytic agent) and Guaifenesin (expectorant). Ambroxol belongs to the class of mucolytic agents (cough/sputum thinner) that works by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nose. Guaifenesin belongs to the class of expectorants that increase the volume of fluid in the airways, reduce mucus stickiness, and remove it from airways. Theophylline which inhibits the enzyme phosphodiesterase 3 and 4, which leads to relaxation of smooth muscles, including those in the bronchi, which leads to their expansion. It also increases the force of contraction of the diaphragm muscles, and inhibits the response of the respiratory tract to any stimulus that causes allergies and respiratory tract infections.
